Contexto local · Mataró
In Mataró natural gas dominates.
Mataró is the Maresme capital and the largest city on Barcelona's north coast. Sea proximity forces siloxane façade paint, stainless hardware and anti-corrosion cylinders on every exterior lock. The old town keeps narrow buildings with spiral staircases that limit material size — we often hoist large furniture up via balcony with pulleys. In the eixample and Cerdanyola, 1960s–80s flats have salt-battered external blinds we replace with marine-coated aluminium. Parking is tough near the centre; we unload first thing in the morning.
